In poetry:

The soft, endearing mien;
Whose looks the heaviest grief beguile,
And chear the gloomiest scene;
May ev'ry Muse her tribute pay,
When thy celestial name demands the lay.
"Ode To Benevolence" by Elizabeth Bentley

Diffused its blessèd warmth and cheer,
Enriching body, mind and soul,
While music floated o'er the stream,
And made such beauty seem a dream.

Diffusing peace o'er all my powers;

In darkest shades, the flames I feel;
To you I trust, and safely may,
The love that wastes my strength away.
"The Secrets Of Divine Love Are To Be Kept" by William Cowper

The verse sublime, the dulcet song;
While round the POET'S seat shall throng, Each rapture sacred to the MUSE;
Still shall thy verdant branches be
The bow'r of wond'rous minstrelsy.
"Stanzas Written under an Oak in Windsor Forest" by Mary Darby Robinson
When I thy parts run o'er, I can't espy
In any one, the least indecency;
But every line and limb diffused thence
A fair and unfamiliar excellence;
So that the more I look, the more I prove
There's still more cause why I the more should love.
"To Perenna" by Robert Herrick
The hushing bounties of those twilight hours
Falling into our souls, as in the flowers’
Balm-breathing bosoms melt the silent dews,
Should freshen every feeling mild and wise
And thence o’er all our charities diffuse
The quiet of the skies.
